摘要
根据锦屏-苏南±800kV特高压直流输电线路900mm2导线的特点,合理地悬挂放线滑车,利用380kN级大型牵引机及3台2×70kN级大型张力机配合,采取"一牵(2+2+2)"的方式进行张力展放,该架线方式可确保大截面导线架线施工的安全、质量,并有效提高了施工效率。
According to the features of 900 mm^2 large-cross-section wires of Jinping-Sunan UHVDC transmission line,with pulley wheels sunpended resonablely,380 kN dragging machine and 2×70 kN tensioning machine are matched and used for tension string construction applying 1-pulling-（2＋2＋2）,which can ensure the safety,quality and constuction efficency.
